| Popis: | In this chapter, circuit level solutions are presented for coping with the impact of process variations. One of the problems associated with process-variation-induced mismatch is the second order intermodulation distortion (IMD2). Based on the system-level analysis of Chap. 2, the overall performance of a receiver is more sensitive to the noise and nonlinearity distortion of the building blocks which contribute more to the total noise and distortion. The contribution of the stages prior to the mixer in a zero-IF receiver to the total IMD2 can be suppressed by filtering. However, the IMD2 generated by the zero-IF mixer lies in the IF band and cannot be filtered. In Sect. 5.1, a tunable mixer is implemented for correcting the mismatches and minimizing the IMD2. Furthermore, since in many of the system-level analyses the IMD3 is presumed as the dominant source of intermodulation distortion, suppressing the IMD2 by this method prevents violating this assumption. |
